Development Of A Web-Based Course Scheduling Information System For The Information Technology Study Program At Universitas PGRI Sumatera Barat

M Egi Alfarizi, Ade Pratama, Rahayu Trisetyowati Untari
Abstract: Course timetable preparation in the Information Technology Study Program at Universitas PGRI Sumatera Barat is still performed in spreadsheets, typically requires three to five days, and can produce instructor, class, or… room conflicts. This study develops a web-based scheduling information system that centralizes timetable data, detects collisions automatically, and offers alternatives with support from the Google Gemini API. Development followed the Waterfall System Development Life Cycle, comprising requirements analysis, design, implementation, testing, deployment, and maintenance. The application was built with PHP, Laravel, and MySQL. A deterministic rule identifies overlapping allocations involving the same instructor, class, or room on the same day. Gemini is used only to rank and explain feasible candidates; the application revalidates each recommendation, and the Study Program Secretary retains final approval. Black-box testing of ten functions achieved a 100% success rate. Beta testing produced an average score of 89.22% from three experts and 89.79% from two users, with both results classified as Very Good. The findings indicate that the system is highly feasible for integrated course timetable preparation and administration.

Design And Development Of A Web-Based Geographic Information System For Road Conditions In Muara Bulian

Maila Rizqi Aulia, Ahmad Syukron Prasaja
Abstract: The development of information technology has significantly influenced information management and dissemination, including in road infrastructure. However, road condition data collection in Muara Bulian is still conducted… d manually, resulting in ineffective data management and limited public access to accurate information. This study aims to design and develop a web-based Geographic Information System (Web-GIS) for road conditions in Muara Bulian. The study employed a descriptive qualitative method using observation, interviews, documentation, and literature review for data collection. The system was developed using the Waterfall model, consisting of requirements analysis, system design, implementation, and testing. The application was developed using Python and the Flask framework, with SQLite as the database and Leaflet.js and QGIS to support interactive map visualization. The results show that the system can display road condition information through interactive digital maps, provide road location search and detailed information, support basemap switching, facilitate road data management, and generate reports. Black Box Testing confirmed that all system functions operated according to the specified requirements. The Web-GIS is expected to support the government in managing road infrastructure data and facilitate public access to road condition information effectively and efficiently.

Cross-Lingual Indirect Prompt Injection Across Retrieval, Reranking, And Generation In Multilingual RAG

Fauzi Bondan Prihananto, Erlangga Bayu Yudho Prakoso, Aprilisa Arum Sari, Tomy Anugrah Islami
Abstract: External evidence can make retrieval-augmented generation (RAG) more informative, yet retrieved passages also provide a path for adversarial instructions to enter the model context. We examine that path in an English-Indonesian… onesian RAG system and track cross-lingual indirect prompt injection separately at retrieval, reranking, and generation. The experiment starts from 75 semantic items and evaluates every item in eight query/body/payload language combinations, for 600 paired trials. Qwen3-Embedding-0.6B and BGE-M3 produce top-20 candidate sets, BGE-reranker-v2-m3 reduces each set to five documents, and Qwen3-0.6B answers from the resulting context with either a standard prompt or an explicit trust-boundary prompt. Statistical uncertainty is estimated by resampling semantic items, and paired binary outcomes are modeled with generalized estimating equations. Poison documents reached the top 20 in 80.50% of Qwen trials and 37.67% of BGE-M3 trials (odds ratio 6.94, 95% CI 4.53-10.63). Top-five exposure was 18.50% and 16.17%, respectively. Standard end-to-end attack success was 6.33% for Qwen and 6.00% for BGE-M3; boundary-aware prompting lowered both rates to 1.33%, with no canary false positives. The results indicate that multilingual RAG security depends on several linked stages rather than generation alone.

Abstract: Statistik produksi perikanan penting untuk memahami perubahan jangka panjang perikanan pelagis kecil, tetapi data tahunan sering belum dimanfaatkan secara optimal karena keterbatasan literasi dan kemampuan interpretasi data.… ata. Kegiatan pengabdian ini bertujuan memperkuat literasi data perikanan mahasiswa melalui analisis produksi ikan tembang (Sardinella fimbriata) di Kabupaten Lamongan, Indonesia, tahun 1990–2024. Kegiatan melibatkan enam mahasiswa Program Studi Ilmu Kelautan, Fakultas Perikanan dan Ilmu Kelautan, Universitas Brawijaya, dengan pendekatan edukatif-partisipatif melalui pengenalan data, pengolahan menggunakan Microsoft Excel, visualisasi deret waktu, latihan perhitungan, interpretasi terbimbing, dan diskusi kritis. Dataset transparan yang terdiri atas 35 observasi tahunan dianalisis menggunakan total dan rata-rata produksi, nilai minimum dan maksimum, perubahan absolut dan relatif antartahun, perbandingan antarperiode, serta Compound Annual Growth Rate (CAGR). Total produksi mencapai 191.156,2 ton dengan rata-rata 5.461,61 ton per tahun dan CAGR keseluruhan 1,87% per tahun. Produksi terendah sebesar 248,5 ton terjadi pada 2009, sedangkan produksi tertinggi mencapai 24.676,8 ton pada 2016. Kenaikan terbesar terjadi pada 2015–2016 sebesar 21.567,8 ton atau 693,72%, sementara penurunan terbesar terjadi pada 2022–2023 sebesar 9.544,1 ton atau 53,84%. Pengamatan deskriptif terhadap luaran pembelajaran menunjukkan bahwa peserta mampu membaca tren produksi, membedakan perubahan absolut dan relatif, membandingkan rata-rata antarperiode dan CAGR, serta menjelaskan bahwa data produksi tidak dapat langsung diartikan sebagai kelimpahan stok ikan. Data perikanan jangka panjang yang transparan dapat digunakan sebagai media pembelajaran kontekstual untuk memperkuat literasi data perikanan yang kritis, sistematis, dan dapat direplikasi.

Procedural Level Generation For 2D Platformer Games Based On Graph And Chunk

Akmal Zidan Fahreza, Chrystia Aji Putra, Yisti Vita Via
Abstract: Level design is one of the key components in determining the gameplay experience in 2D platformer games. However, manual level design is time-consuming and difficult to scale. Graph theory can be used to represent the abstract… stract structure of a level, with nodes as spatial units and edges as paths connecting those spaces. The problem is that this graph structure cannot always be directly translated into a valid and playable physical layout due to platformer constraints, such as jump height, safe distance, and gravity. This research proposes a chunk-based transformation approach, in which each graph node is represented as a fixed-size level chunk containing a platform layout, obstacles, and entry and exit points. The transformation of the graph into a physical level is carried out through the selection, arrangement, and alignment of chunks based on the graph’s topology. This study aims to design a framework for transforming an abstract graph G=(V,E) into a chunk-based 2D platformer level layout. The method used is qualitative-descriptive, involving the formulation of a graph model, rules for mapping and arranging chunks, and playability criteria. The results of the study reveal three main stages: mapping vertices to corresponding chunks, arranging chunks according to the graph’s structure, and validating reachability using an automatic path-finding agent.

LEADERSHIP AND WORK-LIFE AS DRIVING FACTORS FOR EMPLOYEE ENGAGEMENT AND PERFORMANCE

Ohoiwutun, Stanislaus Kostka, Rahawarin, Mohamad Arsad
Abstract: This study examines how leadership and work-life balance influence employee performance directly and indirectly through employee engagement at the Fisheries Service of Central Maluku Regency. A descriptive quantitative,&#8230; causal-correlational design was applied to the entire population of 49 employees using total sampling. Data were analyzed through descriptive statistics, path analysis, and Sobel tests to estimate direct, indirect, and mediating effects. The findings show that leadership significantly affects employee engagement (beta = 0.582; p < 0.001), while work-life balance also has a significant, although smaller, effect on engagement (beta = 0.129; p = 0.005). Employee engagement strongly affects performance (beta = 0.942; p < 0.001). In contrast, the direct effects of leadership (beta = 0.034; p = 0.613) and work-life balance (beta = -0.008; p = 0.756) on performance are not significant. Sobel testing confirms that employee engagement mediates the effect of leadership on performance (p = 0.00015) and the effect of work-life balance on performance (p = 0.03). The model explains 92.4% of the variance in performance. The study's novelty lies in demonstrating, within a local public-sector context, that leadership and work-life balance improve performance primarily by strengthening employee engagement rather than through direct effects. These findings imply that public organizations should prioritize engagement-oriented leadership and work-life policies to achieve sustainable employee performance.
